BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a hair iron for curling, and more particularly, to a wet-and-dry-type hair iron for curling, which has a moisture discharge structure capable of curling hair in a state where hair is wet when hair is curled by heating hair for permanent wave of hair, thereby simultaneously carrying out hair drying and curling when hair is curled just after washed.

Additionally, the present invention relates to a hair iron for curling, which has a power line connection member capable of idling and being freely attached and detached to preventing twisting of a power line, thereby providing convenience in carrying and arrangement.

2. Background Art

In general, a hair iron for curling disclosed in Korean Patent No. 0,562,426 (patented on Mar. 13, 2006) by the same inventor as the present invention has been used in the beauty industry and by the general public.

Typical hair irons are generally dry type hair irons for curling dry hair in such a way that the entire of a heat generation part is in contact with a customer's hair.

Therefore, if hair-forming is applied to wet hair, moisture evaporated by heating cannot be discharged to the outside smoothly.

So, when hair is heated to temperature necessary for forming hair, hair-forming may be interfered since moisture hinders temperature rising of the entire wet hair.

Furthermore, there are various prior arts related with a cable anti-twisting structure of a power source line for electronic appliances:

Korean Utility Model Publication No. 1990-0001560 (Feb. 28, 1990) entitled “Plug and jack of telephone for preventing twist of wire”;

Korean Utility Model Registration No. 0,165,033 (Oct. 13, 1999) entitled “Cord anti-twisting device of telephone”;

Korean Utility Model Registration No. 0,167,150 (Oct. 30, 1999) entitled “Cord anti-twisting structure of handset”;

Korean Patent Publication No. 1999-0021304 (Mar. 25, 1999) entitled “Power cord anti-twisting structure of hair drier”; and

Korean Utility Model Publication No. 1998-0066628 (Dec. 5, 1998) entitled “Power cord for anti-twisting.

Most of the prior arts include a sleeve for receiving and surrounding a cylindrical rotor to realize an anti-twisting structure and an electric connection.

However, since such prior art anti-twisting structures applied to various cables for a power line and a telephone line are generally in a fixed type and cannot be attached and detached via a plug and a jack, they are disadvantageous in packing, safekeeping and carrying.

SUMMARY OF THE INVENTION

As described above, the present invention is proposed to enable a wet type hair forming by solving that it is difficult to form wet hair into a wanted style using a conventional dry type hair curling iron.

Accordingly, to solve the above disadvantages of the prior arts, it is an object of the present invention to provide a wet-and-dry-type hair curling iron, which includes a lever engageably connected to a main body having a grasping part and a heat generation part, the lever having an auxiliary moisture discharge member having a channel and through holes introduced to a pressurizing part engaging with the heat generation part of the main body, thereby smoothly discharging vapor evaporated from wet hair by heating.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Reference will be now made in detail to the preferred embodiment of the present invention with reference to the attached drawings. In the drawings, like reference numerals designate like or similar parts.

FIG. 1 is a perspective view of a hair curling iron (I) according to the present invention, and FIG. 2 is an exploded perspective view showing a state where the hair curling iron (I) of FIG. 1 is rotated at an angle of 180°.

As shown in the drawings, the hair curling iron (I) according to the present invention includes: a main body 210; and a lever 220 combined with the main body 210 through a rotary shaft pin 222 at the boundary between a heat generation part 213 and a grasping part 211.

The combination of the main body 210 and the lever 220 has a form similar to scissors, but the lever 220 combined with the main body 210 pivots on the rotary shaft pin 222 in such a way that the heat generation part 213 of the main body 210 and a pressurizing part 223 of the lever 220 engage with each other without crossing each other.

Another hair curling iron (I) shown in FIG. 8 has the same moisture discharge supporting member, anti-twisting structure, and attaching and detaching concept as the iron shown in FIGS. 1 to 4, which are the cores of the present invention, but has a different lever structure from the iron of FIGS. 1 to 4. In FIG. 8, a lever 320 includes a pressing part 325 for pivoting a pressurizing part 323 on a rotary shaft pin 322 of a connection part 321, the pressing part 325 being located in the same direction as the pressurizing part 323 engaging with a heat generation part 312 of a main body 310.

The rotary shaft pin 322 has a spring (not shown) mounted therein so as to provide elasticity to always keep engagement between the pressurizing part 323 of the lever 320 and the heat generation part 313 of the main body 310 when the external force is not applied.

The rotary shaft pins 222 and 322 shown in FIGS. 1 and 8 serve as rotary shafts for the levers 220 and 320, facilitate assembly between the main body and the lever since they have elasticity.

Moreover, each rotary shaft pin serves as a hanger for allowing a user to hang the iron on a holder when the user does not use the iron (I) but conducts other work, so that the user can do other work freely and easily.

The grasping part 211 of the main body 210 has a idle tube 211A combined on the outer periphery of a central rod 211B in order to easily wind hair on the heat generation part 213 of the main body 210 for curling hair.

Moreover, the above function may be achieved by a idle member 213A disposed at an end portion of the heat generation part 213 having an electric heating body 214 therein and a idle tube 225A disposed on the outer periphery of a central rod 225B at the pressing part 225 of the lever 220.

The idle member 213A disposed on the end portion of the heat generation part 213 has radial slots 213 a.

Since hair can be inserted into the slot 213 a, if the main body 210 is rotated on the idle member in a state where the idle member 213A is in contact with hair, the main body is rotated but the idle member 213A is not rotated along with the main body by hair inserted into the slots 213 a, so that the user can more easily wind hair on the heat generation part 213 of the main body 210.

Furthermore, the idle function may not be used according to hair forming types.

Considering the above, the idle tube 211A of the grasping part 211 of the main body 210 includes a locking member 212.

The locking member 212 includes: a button 212A formed between the grasping part and the heat generation part in such a way as to be freely moved by the user's thumb laterally; a fitting hole (not shown) formed on the inner periphery of the idle tube 211A for inserting a fitting end portion (not shown) of the button when the button is pushed toward the idle tube 211A; and a locking position mark 212B formed on the outer periphery of the idle tube for allowing the user to easily check a position of the fitting hole of the idle tube (see FIG. 1).

For convenience in manipulation, a temperature control dial 215 b and a power on/off button 215 a (see FIG. 1) are formed at the portion of the main body 210 on which the button 212A is formed.

Next, another locking member 226 is formed on the idle tube 225A of the pressing part 225 of the lever 220.

The locking member 226 is mounted at a portion where two symmetric brackets 221 a of the connection part 221 of the lever 220 meet with each other, and includes: a guide rail 226B formed at a start point of the central rod 225B of the pressing part; a guided tube 226A laterally moving along the guide rail 226B in a state where it is prevented from separation; and a corresponding joining portion 225 a formed at a portion of the inner periphery of the idle tube 225A in such a way as to engage with a joining portion 226 a of the guided tube 226A in a form of male and female.

The idle tube 225A of the pressing part 225 of the lever 220 is assembled to the lever 220 in such a way that the idle tube 225A is fit onto the central rod 225B and a tightening nut 225 b′ is joined and tightened to a bolt 225 b of an end portion of the central rod 225B, whereby the idle tube 225A is close toward the guided tube 226A.

The lever 220 is combined with the main body 210 in the steps of inserting the main body 210 to the connection part 221 having the two brackets 221 a, inserting and fitting both end portions 222 a of the rotary shaft pin, especially, elastic rotary shaft pin 222, into holes 221 b of the brackets 221 a at the boundary formed between the grasping part and the heat generation part of the main body 210, and inserting the end portions of the rotary shaft pin into two shaft pin insertion holes 213 b of the heat generation part 213 of the main body 210.

Therefore, when the user presses the pressing part 225, the pressurizing part 223 pivots on the rotary shaft pin 222, and the lever 220 engages with the heat generation part 213 of the main body 210.

It is preferable that the pressurizing part 223 has curvature corresponding to the heat generation part 213 of the main body 210, and so, the inner surface of the pressurizing part 223 is in contact with the entire surface of the heat generation part when it engages with the heat generation part.

Like Korean Patent No. 056426 invented by the same inventor as the present invention, to curl hair more rapidly by using heat generated from the heat generation part and the electric heating body of the main body, and to enhance hair curling quality by transmitting heat uniformly to hair located between the pressurizing part of the lever and the heat generation part of the main body, it is preferable to embed an electric heating body 224 in the lever. For this, an electric wire 223 b extending from a power line 30 of a cord (c) must be extended from the heat generation part 213 of the main body 210 to an electric wire 223 b′ for the electric heating body 224.

The hair curling iron (I) according to the present invention is characterized in that an auxiliary moisture discharge member 230 is arranged on the inner surface of the pressurizing part 223 of the lever 220 to realize a wet-and-dry-type iron.

The auxiliary moisture discharge member 230 has a channel 231 formed in a longitudinal direction of the lever, whereby moisture evaporated from wet hair by heating of the two electric heating bodies 214 and 224 can be discharged to the air along the channel.

Furthermore, the channel 231 of the auxiliary moisture discharge member 230 has a number of through holes 233, and the pressurizing part 223 of the lever 220 has discharge holes 223 a corresponding to the through holes 233, so that evaporated moisture can be discharged more smoothly.

The auxiliary moisture discharge member 230 serves as a cover for the electric heating body 224 of the pressurizing part 223 of the lever 220.

The form and the number of the channel and the through holes may be changed by those skilled if necessary.

Next, anti-twisting means (T) of a power line connection member (L) and attaching and detaching means (A) for attaching and detaching the power line to and from the hair curling iron will be described.

First, in the hair curling iron (I) shown in FIGS. 1 to 4, the anti-twisting means (T) is mounted on the cord (C) having the power line 30.

However, in the hair curling iron (I) shown in FIGS. 5 to 7, the anti-twisting means (T) is mounted on the iron (I).

For your reference, the standard of directions of the anti-twisting means and the attaching and detaching means will be specified referring to FIGS. 1 and 3.

In the anti-twisting means formed by combination of an idle projection member 10 and a socket 20, a direction that a jack 27 of the socket 20 is coupled with a plug (L1) of the power line connection member (L) of the iron (I) is defined as a front direction, and the opposite direction of the front direction is defined as a rear direction.

As shown in FIGS. 1 to 4, the idle projection member 20 of the anti-twisting means (T) is connected with the power line 30 of the cord (C).

The jack 27 of the socket 20 coupled with the idle projection member 10 is coupled with the plug (L1) of the power line connection member (L).

The jack 27 and the plug L1 constitute the attaching and detaching means (A).

The power line 30 includes: a main plug formed at an end portion thereof and coupled with a power socket (not shown) equipped in a living room, a bath room, or another room, particularly, a main plug 30A (see FIG. 1) for a three-phase power source; a copper wire 31 (see FIG. 4); an insulating covering 33 surrounding the copper wire 31; and an outer covering 35 for covering the insulating covering 33.

In FIGS. 3 and 4, the idle projection member 10 is disposed at the other end portion of the main plug 30A and has two contact members 13 and 15 arranged concentrically.

The two contact members 13 and 15 of the idle projection member 10 are connected with each other in the form of a

shape, and a damage preventing bellows portion 10 b and a hanger ring 10 a are formed at a bended portion of the connected area between the two contact members 13 and 15. At this time, the damage preventing bellows portion 10 b is thicker than the outer covering 35.

The first contact member 13 of the idle projection member 10 is directly connected with the copper wire 31 of a straight power line in a projection type.

Particularly, a projection 13A of the first contact member 13 is empty and serves as an insertion hole 13 a for the copper wire 31. The copper wire 31 inserted into the projection 13A is fixed by soldering, and is a conductor.

An insertion member 13B made of a non-conductor material and serving to surround the projection 13A and hide the exposed copper wire 31 may be formed in such a way as to mold melted synthetic resin after inserting the projection 13A into an insertion hole 11 a of a housing 11, or previously formed with a separate member.

The insertion member 13B has a direction specifying slot 13 b corresponding to a direction specifying projection 11 b of the housing so as to help a firm fixation of the first contact member 13 coupled with the housing 11.

The second contact member 15 of the idle projection member 10 includes a ring type contact portion 15 a and a connection piece 15 b integrated with the contact portion.

The contact portion 15 a is mounted on the outer periphery of a mounting portion 11 c of the housing 11, and the connection piece 15 b is inserted into a fitting slot lid of the housing 11, and then, the copper wire 31 of another power line is soldered to an end portion of the connection piece 15 b.

The housing 11 of the idle projection member 10 has the insertion hole 11 a for the first contact member 13 as described above.

The front side of the insertion hole 11 a has the shape and inner diameter as large as the insertion hole 11 a can accommodate the projection 13A of the first contact member 13 in contact with the projection 13A, and the rear side thereof has the size and shape as large as the insertion hole 11 a can accommodate the remaining portion of the insertion member 13B excepting the outer portion of the direction specifying slot 13 b.

The housing 11 has a form for combining with cases 29A and 29B which are fixing means for restricting the coupled state between the idle projection member 10 and the socket 20 while allowing the idle projection member 10 and the socket 20 can be rotated idly. For this, the housing 11 has a separation preventing projection 11A formed on the front of the outer periphery thereof and a separation preventing groove 11A′ coupled with separation preventing jaws 29 b of the cases 29A and 29B.

Moreover, the housing 11 has a ring-shaped holding jaw 11B and a holding groove 11B′ formed at the rear thereof. An inward projection type front end portion 10 c extending from the damage preventing bellow portion 10 b of the idle projection member 10, namely, extending from the outer covering 35 of the power line 30, for preventing exposure of the connection state between the first and second contact members 13 and 15 and the copper wire to provide an insulation function is fit to the holding jaw 11B and the holding groove 11B′ so as to prevent separation of the idle projection member 10 and the housing 11.

Next, referring to FIGS. 1 and 3, the socket 20 having first and second coupling members 23 and 25 respectively connected with the first and second contact members 13 and 15 of the idle projection member 10 will be described.

The socket 20 has the jack 27 arranged at the front of a socket body 21. The jack 27 is a typical jack generally used in electronic appliances.

The jack 27 includes: contact sleeves 27 a made of a conductor material, each contact sleeve having an empty inside; and fitting holes 27 b to which a number of pins (L2) (two pins in the drawings) of the plug (L1) of the power line connection member (L) are inserted.

At the rear of the contact sleeves 27 a, the first coupling member 23 connected with the first contact member 13 of projection type and the second coupling member 25 connected with the second contact member 15 of ring type are respectively joined and arranged through connection portions 23 b and 25 b.

Particularly, the first and second coupling members 23 and 25 are elastic pieces curved roundly and having elasticity, whereby contact portions 23 a and 25 a for the first and second contact members 13 and 15 of the idle projection member 10 surround the outer periphery of each contact member.

As described above, the cases 29A and 29B as shown in the drawing can fix the combination between the contact members 13 and 15 of the idle projection member 10 and the coupling members 23 and 25 of the socket 20, namely, prevent twisting of the cord by guaranteeing a relative idle between the idle projection member and the socket.

Particularly, to guarantee water-tightness between the contact surfaces of the two cases 29A and 29B, one of the cases has a projection (not designated in the drawing) and the other has a recess (not designated) in such a way as to be coupled with each other in a male and female form. The two cases are assembled with each other, and then, bonded with each other by an ultrasonic melting method which is a common bonding method.

As described above, the separation preventing jaw 29 b which is inserted into the separation preventing groove 11A′ of the housing 11 of the idle projection member 10 is formed at the rear (left side in the drawing) of each case.

Moreover, an oval shaped separation preventing jaw 29 c which will be inserted into an oval shaped separation preventing groove 21 a formed at the rear of the body 21 of the socket 20 is formed at the front of each case (right side in the drawing).

A support flange 29 a having a support recess 29 a to which the first contact member 13 of the idle projection member 10 is inserted is formed between the separation preventing jaws 29 b and 29 c, so as to guarantee stable combination and idle between the idle projection member and the socket.

For your reference, the reference numeral 29 d in FIG. 3 designates a projection coupled with a recess 27 c formed on the outer periphery of the jack 27.

The separation preventing groove 21 a of the body 21 of the oval shaped socket 20 and the separation preventing jaw 29 c of the cases 29A and 29B function as mounting direction restricting means for specifying an assembling direction of each part.

Next, the hair curling iron (I) shown in FIGS. 5 to 7 will be described.

The hair curling iron shown in FIGS. 5 to 7 has anti-twisting means (T) disposed on the iron (I), differently from the hair curling iron shown in FIGS. 1 to 4.

For your reference, the standard of directions of the anti-twisting means and the attaching and detaching means will be specified referring to FIGS. 5 and 7.

A direction that a jack 131 disposed at an end portion of a power line 130 is coupled to a plug (L1) arranged on an idle projection member 110 is the front, and the opposite direction is the rear.

As shown in FIGS. 5 to 7, in the hair curling iron (I) according to the present invention, the plug (L1) and the jack 131 constitute attaching and detaching means (A), the idle projection member 110 and intermediating means 120 constitute anti-twisting means (T), and a connection member (L) of the power line 130 includes the attaching and detaching means (A) and the anti-twisting means (T).

The power line 130 of a cord (C) having the jack 131 coupled with the plug (L1) at an end portion thereof includes a main plug formed at the opposed end portion of the jack 131 and coupled with a power socket (not shown), which is equipped in a living room, a bath room or other room, particularly, a main plug 135 for a three-phase power source. A copper wire of the cord (C) is surrounded with a double insulating covering 137.

The idle projection member 110 constituting the anti-twisting means (T) together with the intermediating means 120 includes a housing having a front part 110F and a rear part 110R for easiness of assembly.

The rear part 110R has an insertion portion 110C which will be coupled with the jack 131, and holes (not designated) to which two contact pins (L2) of the plug (L1) will be inserted.

Furthermore, the rear part 110R further has an inward projection type front end portion 110D coupled with a holding groove 110B′ formed by a ring type holding jaw 110B of the front part 110F.

The front part 110F has an insertion hole 110 a for a first contact member 113A.

The front side of the insertion hole 110 a has the shape and inner diameter as big as the insertion hole 110 a can accommodate the first contact member 113A in contact with the first contact member 113A.

The rear side of the insertion hole 110 a has the size and shape as big as the insertion hole 110 a can accommodate one (L2 a) of the contact pins of the plug (L1) and the remaining portion excepting the outer portion of a direction specifying slot 111 b′ of a covering 111 b surrounding the first contact member 113A.

The front part 110F includes a separation preventing projection 110A and a separation preventing groove 110A′ formed on the front of the outer periphery thereof for coupling elastically pressurizing members 127A and 127B of fixing means 127 to provide resistance when the idle projection member 110 and the intermediating means 120 are separated from each other.

The front part 110F further includes a ring type holding jaw 110B and a holding groove 110B′ formed at the rear thereof, and the inward projection type front end portion 110D of the rear part 110R is fit to the ring type holding jaw 110B and the holding groove 110B′ to prevent separation of the front end portion of the rear part 110R fit to the rear of the front part 110F.

The idle projection member 110 has two contact members 113A and 113B which are concentric with each other and cut off from electric contact with each other.

The first contact member 113A is a projection type and has an insertion hole 113 a to which an end portion of a connection line 111 a is inserted and which is soldered.

The other end portion of the connection line 11 a is connected with the projection (L2 a) of the plug (L1).

The connection line 111 a is surrounded by the covering 111 b.

The covering 111 b has a direction specifying slot 111 b′ corresponding to the direction specifying projection 110 b of the front part 110F of the housing of the idle projection member 110, thereby helping a firm fixation of the first contact member 113A connected to the front part 110F of the housing.

The second contact member 113B includes a ring type contact portion 113 b and a connection piece 113 b′ integrated with the contact portion.

The contact portion 113 b is connected to the outer periphery of a front part mounting portion 110 c of the idle projection member 110.

The connection piece 113 b′ is fit into the fitting hole 110 d of the housing 110 and soldered with another connection line 111 c, and the rear end portion of the connection line is also soldered with another projection (L2 a) of the plug (L1).

Next, referring to FIGS. 6 and 7, the intermediating means 120 having first and second coupling members 123 and 125 for the first and second contact members 113A and 113B will be described.

It is preferable that the intermediating means 120 is mounted in a specified direction for easiness in assembly when it is mounted on the hair curling iron.

For this, it is preferable to adopt mounting direction restricting means to the intermediating means 120.

In the drawings, the mounting direction restricting means includes a restricting piece 121 a and two restricting projections 121 b formed at the front of a body 121 thereof. Alternatively, the mounting direction restricting means may be embodied by forming the intermediating means in an oval shape.

The first coupling member 123 of the intermediating means 120 for the first contact member 113A is located at the front of a mounting portion 121A of the intermediating means body 121, and the connection piece 123 a of the first coupling member 123 is exposed forwardly from the outer periphery of the body 121 after passing through a slit 121 c of the body 121.

The front end portion of the connection piece 123 a has a connection hole 123 a′ to which a connection line 122 for introducing electric power to the hair curling iron is inserted and which is soldered.

The connection piece 123 a has a fixed projection 123 b pressurized at a portion adjacent to the slit 121 c of the body 121 so as to prevent separation of the first coupling member 123 coupled with the body 121.
